The Lowdown
G’day, Rusty here again. Let’s get into the same stretch but in feet and miles, because that’s how some of us think. Jaconé’s looking like a proper mixed bag over the next couple of weeks – some clean days, some duds, and a couple of real standouts if you time it right.
First surf worth paddling out for kicks off Monday morning – light rain, cross-on breeze, but the swell’s around 8ft from the S with an 11-second period. Energy’s strong at 1579, so there’s push. Water temp’s about 72.5°, which is normal for this time of year. It’s a bit bumpy, but okay for the locals. Monday afternoon flips to glassy with an ENE breeze, swell drops slightly to 7.5ft from SSW, period 10s, energy 1113 – clean and glassy, that’s your first standout. Best session of that day.
Tuesday morning has a NE offshore at 9 mph, swell 5ft from S, 10s, energy 662 – clean and fun. Tuesday afternoon gets a bit breezier (12 mph cross-off), still clean, energy 613. Wednesday is small – 3.5ft morning, 3ft afternoon – glassy windows but weak energy (352 and 262). Thursday morning is clean with 4ft from S at 12s, energy 486, light air – okay, but nothing big. Thursday afternoon is a write-off with WSW onshore breeze. Friday morning is a real highlight: clear skies, N cross-off, 4ft from S but with a 14-second period, energy 703 – proper groundswell, clean and lined up. Friday afternoon stays okay but cross-shore, energy 585.
Saturday’s a mess – ENE swell at 6ft but only 8 seconds, lumpy, cross-shore, energy 700. Saturday afternoon is a full dud – 2ft, 15 mph cross-on, energy 179. Sunday brings a bigger pulse – 8ft from SSW at 12s, energy 1672 in the morning; afternoon holds 7.5ft, energy 1795, with a cross-off breeze, cleaner and more powerful.
Now the big one – Monday the 14th. Morning has NE offshore at 15 mph, 8ft from S with a 13-second period, energy 2330 – strong, clean, lined up. This is the best wave of the run. Afternoon holds the same size and period, energy 2189 – still excellent. If you only surf one day, make it this one.
Tuesday the 15th fades: morning cross-on, 6ft, energy 1157; afternoon swings NE offshore at 9 mph, 5ft from SSE, 12s, energy 926 – clean but smaller. Wednesday the 16th is small and onshore – skip it. Thursday the 17th – morning 4.5ft, 9s, onshore, poor; afternoon improves to 5.5ft from S at 12s, cross-shore, energy 857 – surfable but nothing special.
Friday the 18th brings the next serious swell – morning 8ft from S, 15-second period, energy 3278, clean cross-off. That’s big and lined up. But afternoon jumps to 10ft, energy 4275 – overhead-plus, only for experts, and cross-shore wind adds some chop. Stay out unless you’re solid. Saturday the 19th eases to 7.5ft in the morning, energy 2406, clean; afternoon drops to 6.5ft, energy 1751, still good. Sunday the 20th fades – morning 4ft, cross-on, energy 972; afternoon has a weird ESE pulse at 7ft but only 9 seconds, energy 976 – junky. Monday the 21st is small and messy. Tuesday the 22nd has fresh offshore ENE at 18 mph, but the swell’s only 5ft from E at 9s – windy and small, not worth getting wet for.
Your two true standouts are Monday the 14th – offshore, clean, solid south swell – and Friday the 18th afternoon for the hardcore crew, though that one’s a big-wave session. Jaconé’s consistent, so when the conditions line up, it fires. Crowds are sometimes a factor – expect company on the

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
